Mourning is a fundamental mechanism for our psychological dynamics. The mourning process attempts to transform an irreversible process such as the passing of time into a reversible one, where the moment of loss is re-enacted and elaborated. In thermodynamics the inevitable increase of entropy for every complex system makes it impossible to invert the direction of time. However our brain, via the mourning, is performing such a time inversion. This paper explores the conditions under which such a process is possible and the implications in terms of entropy of considering thoughts as physical objects. A possible formalisation of this process is suggested using the formalism of chaos theory, as it probably presents a very high degree of nonlinearity.
